CAP FOR JARS AND" THE LIKE Filed Oct. 20, 1928 Patented Feb. 4, 1930 UNITED STATES PATENT OFFICE ALBERT e. nnsnnmor WATERBURY, connnc'ncnr, assrenon 'ro scovrm. MANUFAC- OUT TUBING COMPANY, OF WATERBURY, CONNECTICUT, A CORPORATION OF CONNECTI- CAI son sans AND THE Lin Application filed October 20, 1928. ISM-19.1 No. 813,878.

. This invention relates to improvements in I secured to the jar, so that it can be taken off and replaced and yet be firmly held in position. It is further desirable in this class of jars that the cap have an ornamental appearance or a fine finished surface, such as produced by plating.

Where such a cap is to be employed, means must be provided for removably securing the cap in position, and where an ornamental cap is employed, the securing means should be of such a character that they are concealed by the cap when the cap is on the jar.

It is the special object of the present invention to produce a cap for jars and the like having an ornamental appearance, said cap being provided with means concealed within the cap for locking'it to the jar, so that the locking means are out of sight when the cap is in position.

A further object of the invention is to produce an improved means for securing together the cap and its locking device, so as to permit ready and quick assemblage.

With these and other objects not specifically referred to, the invention consists in certain novel parts, arrangements and combinations which will be described in connec' tion with the accompanying drawings and the novel features pointed out in the claims hereunto annexed.

Referring'now to these drawings- Fig. 1 is a perspective view of the improved cap showing the locking devices for locking the cap to a jar.

Fig. 2 is an enlarged sectional view, taken on line 22 of Fig. 1, showing the cap applied to a jar, the latter being shown broken away; and

t Fig. 3 is a perspective view of a preferred means for securing the cap and the cap locking devices together.

Referring to said drawings, the container with which the cap is used is illustrated as a glass jar, marked-1, having a wide mouth 2. It. is to be understood, however, that the jar shown is merely, illustrative, and .that the ca has been designed for and made for use witii jars of other shape and made of other materials.

In accordance with the invention, this jar is closed by a meta. cap. havin a top 3 and a side flange 4 which extends own over the sides of the jar. This top and flan e of the cap may be ornamented in any suita 1e manner, as by decorating with a lacquer desi n, or by finishing with nickel plate or the li e. This cap is removably held on the jar, so that it can be removed and replaced, and to effect this, the jar is provided with lips or rid es 5 with which coo erate certain fastening evices carried wit in the cap, so as to be concealed thereby. While these devices ma be of various forms, in the construction illustrated, there is provided a shell 6 having a top 7 and a side flan e 8 substantially coextensive with the side ange 4 of the cap. The walls of this shell are punched inwardly to form projections 9 adapted to be brought into locking relation with the lips 5 by a relative rotation of the ca and jar.

The shell 6 is secure to the cap in any suitable way. In the best constructions, and as shown, the inside of the cap has soldered thereto a. plate or spider 10of Iight metal which is formed with tongues 11. The surface 7 of the shell is slotted, as indicated at 12,

and the tongues are passed through these slots and bent under the under surface of the top of the shell, as shown at 13. With this construction, the parts are securely locked together, and all the locking mechanism is con-' cealed beneath the flange 4 of the cap so as to be invisible when the cap is formed. In assembling, the spider or plate is first secured to the shell, so that the cap can be finished as desired, the parts then, after such finishing, being soldered together.

While the invention has been shown and describedin its preferred form, it is to be understood that various changes and alterations may be made in the specific construction and arrangement shown without departing from the invention as defined in the accompanying claims.

What is claimed is:

1. A j error the like having a mouth, a cap closing the jar, a shell within the cap having means for securing the cap to the jar, a plate intermediate the cap and shell, grooves in the shell, tongues on the plate engaging the grooves for locking the plate and shell together, ,and means for securing the plate to the shell.

2. A jar or the like having a mouth, a cap closing the jar and having a'depending flange,

a shell within the cap having a flange substantially (so-extensive with the .cap'flange,

means on the shell flange for ,securing thecap to the jar, a plate intermedlate the cap and shell, complementary tongues and grooves on the shell and plate for locking them together, and means for securing the plate in the cap.

3. A jar or the like having a mouth, a cap closing the jar and having a depending flange,'a shell within the caphaving a flange substantially coextensive with the cap flange,

means on the shell flange for securing the cap to the jar, andmeans for securing the cap and.

shell together.

- 4. A jar or the like having a mo'uth, a cap having a depending flange closlng thejar, a member within the .cap having means for securing the cap to the jar, and an intermediate device within the flange between the cap and member for securing the latter together with the member beneath the cap.

5. A jar or the like having a mouth, a cap closing the jar, a shell within the cap having means fors'ecuring the cap to the jar, a plate intermediate the cap and shell, complementary tongue and groove devices for securing the plate and shell together, and means top and provided with means for securing the for securing the plate to the shell.

6. A jar or the like having a mouth, a cap closing the ar and having a depending flange, .a shell within the cap'having a flange, means on the shellfi ange'foi securing the cap to the jar, and means for locking the cap and shell to ether.

A jar or the like having a mouth, a cap 1 closing the jar and having a depending flange, a member within the cap having a fiat cap to the jar, a flat intermediate member between the cap and the flangedmember, means for securing the flanged member and intermediate member together, and means for securing the intermediate member to the under side of the cap.

In testimony whereof, I have hereunto set my hand. I
